Sorry that you've been ripped off by one of the many used remote control resellers on E-bay. Unfortunately these unsavory characters are aware that they are selling landfill, but cover themselves with the line that potential buyers should first check with their dealers knowing full well that few will do so before bidding. If you would go back and claim they knowingly sold you a useless remote, they will simply claim ignorance and advise that's why they told you to check with your dealer first. The only thing you can do is to leave appropriate feedback to warn other potential buyers. It seems that when most folks discover they've been ripped off, they somehow don't want to leave feedback , and so others are victimized.
